IMPROVEMENT IN VEHICLE DEVICES FOR STOPPING HORSES.

Specification forming part of Letters Patent No. 174,472, dated March`7, 1876; application iiled February 25, 1876.

y In the former patent the checking arm is carried by a movable bearingpiece or bracket,

to which is attached a carriage-step, and the sector is arranged back ofthe hub, and the step turns. In the latter patent the sector of the checkin g-arm is placed immediately above the hub, and is depressed to engage the sector with the hub by means of a lever.

In this our present invention the shaft supporting the checking arm and sector is mounted on a hinged step box or frame ati tached to the upper side of the` axle, immediately back of the hub, the box-top answering for the step to receive the foot, and by steppmg on the box, in getting out of the carriage,

, the sector of the checking-arm is thrown down into engagement with the flange on the hub.

Our present invention consists in the combination of the checking-arm and-sector with a hinged step-box adapted to be applied to the top of the axle; also, in the combination, with the checking-arm and sector, of a spring or yielding tooth, so that the checking arm will not be operated when the carriage is moved backward.

Figure l is a sideA view of our checking mechanism shown as connected with a bit in the mouth of a horse. Fig. 2 is a section in part of our invention.

A is the axle, to which the checking device toothed rim or lis attached by means of clips a.. The hub bis shown in section, and is to be provided with two'ormore sections of teeth, c, as shown in ouil other/patents; but in this instance we have shown but one section. The step-box Bconsists of a frame, d, set on the axle, having pivoted thereto, at c, a lid or plate, f, whichv sustains a shaft, g, to which the checking arm Y or lever h, with its attached cogged sector a',

is attached. yA strong' barrel-spring, j, has its yinner end connected with the lshaft g'andv its outer end with the lid f, and the tendency of the spring is to turn the shaft and arm to the position shown in full lines, Fig. l, or so that it will not draw on the checking-strap 7c, which is connected with a ring, l, attached to a bitstrap, m, adapted to be attached to the bitn in the month of the horse. Any other suitable spring might be used instead of the barrelspring-as, for instance, a wire or coiled spring. A spring, o, within the step-box lifts the lid f, when the spring-hook p ispushed back out of engagement with the bottom of the step-box. .A person stepping out of the,

jerked in this way two or more times during' Veach rotation of the hub forward, accordinglyas there are two or more sections of teeth, c.

Should the carriage be Amoved backward the teeth of c will tirstimeet the loose spring-tooth r, and the sector and arm h will not be operated. This is of much importance, for when a horse starts to back he should not be urged to back farther. In getting into or when in the carriage the projection s may be pressed back to knock off from corner q the hook p, and then the spring o will elevate the lid of the step-box. The dotted lines, Fig. 1, show the position of the checking-lever when drawn back by the action of the teeth c on the sector t. The surface of the lid of the step-box is preferably roughened. The ring L is attached to the bit-strap m at oneside of its center to insure an even pull. l
